Payment issues?
If you see 'payment blocked' or 'too risky', this is Stripe's automated fraud prevention — not a merchant decision. Common causes and fixes:
1. VPN / Proxy Turn off your VPN or switch to a node matching your card's issuing country. IP-to-card country mismatch often triggers the block.
2. Card not enabled for international payments Make sure your credit/debit card has international online transactions enabled — some banks disable this by default.
3. Try a different card Prefer Visa / Mastercard credit cards. Prepaid or virtual cards are more likely to be blocked.
4. Browser issues Try incognito/private mode, or a different browser. Some extensions can interfere with the payment flow.
5. Still not working? Contact the author via Alipay or PayPal to complete the payment.
